Dap’s newest wall and floor sealant, Sound Block E90, is designed specifically to reduce sound transmission through penetrations in wall and floor systems, as well as improve STC ratings in sound-rated applications. The sealant is recommended for use with openings around electrical boxes, pipes, duct systems, cut-outs, and other types of penetrating utility equipment, and for abutting surfaces, corner joints, and other perimeter edges. Sound Block E90 is sold in 28-fluid-ounce plastic cartridges designed for easy gun application. Pricing starts at $6. dap.com
